Hello I have a metal to metal rattle when I hit a bump I replaced the sway bar links and sway bar bushings does anyone have a clue to what this may be the dealer is playing pick a part ..........thanks

sounds like your missing some antirattle clips in your front brake calipers... when you have the brakes applied it will apply pressure to the loose pads and prevent them from knocking around... That would be the first place I looked.
